Arlington's municipal water contains more chlorine than a swimming pool.

Why Filter Your Water in Arlington?
Do you notice your tap water tastes off, smells like chlorine, or leaves white, crusty deposits on your faucets? These are common signs that your water quality could be improved. The chlorine smell is from disinfectants that, while necessary for safety, make water unpleasant to drink and can affect the taste of coffee and ice. The scale buildup is from dissolved minerals that can damage fixtures and appliances over time.

Health Benefits You Can Feel
Beyond better taste, filtration offers significant health benefits. Many Arlington residents report improvements in their skin and hair, as filtering removes drying chemicals like chlorine. However, the most critical reason to filter is to remove contaminants you can't see, taste, or smell.
- Lead: A serious risk in older Arlington homes (pre-1986) with lead pipes or solder, it has severe health effects, especially for children.
- Pesticides & Chemicals: Agricultural runoff, industrial byproducts, and pharmaceutical residues can enter the water supply.
- Bacteria: Giardia and Cryptosporidium can sometimes bypass municipal treatment.
While Arlington's water meets basic EPA standards, thousands of unregulated contaminants may still be present. An under sink water filter arlington va puts you in control of your family's water quality. Concerns about "forever chemicals" are also growing; our guide to a PFAS Removal System in Arlington VA explains how specific filters can help. To learn more, see our article on the Importance of Water Treatment.
Filtering is a practical step to protect your family's health and ensure the water you use for drinking, cooking, or preparing baby formula is clean and safe.
Point-of-Use Water Filtration: Countertop vs. Under-Sink Options
Two popular point-of-use options for your kitchen are countertop filters and under sink water filter arlington va systems. The right choice depends on your space, filtration needs, and installation preference.
Countertop filters are easy to install, often attaching directly to your faucet. This makes them a good choice for renters or those seeking a simple, portable solution. However, they occupy valuable counter space and typically offer less comprehensive filtration than under-sink models.
An under sink water filter arlington va system is a more permanent solution installed discreetly in the cabinet beneath your sink. This keeps countertops clear for a clean, minimalist aesthetic. Under-sink filters, particularly Reverse Osmosis (RO) systems, provide powerful multi-stage filtration certified to reduce over 90 contaminants. They connect to a dedicated faucet, delivering a virtually unlimited supply of purified water on demand.
While installation is more involved—requiring plumbing connections and a hole for the dedicated faucet—professional installation ensures a leak-free, reliable setup. The trade-off of some cabinet space is often considered worthwhile for superior filtration and an uncluttered kitchen.
Let's break down the key differences:
| Feature | Countertop Filters | Under-Sink Filters |
|---|---|---|
| Kitchen Space | Occupies countertop space | Discreetly installed under the sink, saves counter space |
| Installation | Very easy, usually attaches to existing faucet | More complex, requires plumbing modification, dedicated faucet |
| Filtration | Varies, often less comprehensive than RO | Often multi-stage, including RO, for comprehensive contaminant removal |
| Aesthetics | Visible on countertop, can clutter the kitchen | Hidden from view, maintains clean kitchen aesthetics |
| Capacity | Generally lower flow rate, smaller filter capacity | Higher flow rate, larger filter capacity, virtually unlimited supply |
For most Arlington homeowners investing in their property, an under-sink system offers the most thorough protection. You can explore all your options and see which filtration technology fits your needs best on our Water Filtration Systems page.
A Closer Look at the Best Under Sink Water Filter in Arlington VA
For the best under sink water filter arlington va offers, Reverse Osmosis (RO) systems are the gold standard. These sophisticated systems fit neatly under your sink to deliver exceptionally pure water.

RO systems use a multi-stage filtration process. First, a sediment filter traps large particles like dirt, sand, and rust. Next, an activated carbon filter removes chlorine, chloramines, and other chemicals that cause bad tastes and odors. The core of the system is the RO membrane, which uses pressure to force water through microscopic pores, removing up to 99% of dissolved solids, heavy metals (lead, arsenic, mercury), fluoride, bacteria, and viruses. A final post-carbon filter polishes the water for a crisp, clean taste. Our systems are certified to reduce over 90 contaminants, providing a virtually unlimited supply of safer water.
How an under sink water filter improves water quality
An under sink water filter arlington va transforms your daily water experience. You'll immediately notice a dramatic improvement in taste and odor, as chlorine and metallic tastes are eliminated. This improves everything from a simple glass of water to your morning coffee and cooked meals. For parents, it provides peace of mind when preparing baby formula.
Beyond taste, these systems provide significant health benefits by reducing heavy metals like lead, which is a concern in older Arlington homes. They also remove unseen chemicals and pharmaceutical residues that can enter municipal water supplies. Explore the benefits on our Water Filtration page.
Comparing an under sink water filter in Arlington VA to a whole-house system
It's important to distinguish between point-of-use and point-of-entry systems.
- An under sink water filter arlington va is a point-of-use solution, targeting the water at your kitchen sink for the highest purity in drinking and cooking water.
- A whole-house system is a point-of-entry solution, treating all water as it enters your home. This protects every faucet and appliance from chlorine, sediment, and hard water minerals, improving appliance longevity and water quality for bathing.
While an under-sink RO system provides the purest drinking water, a whole-house system protects your entire plumbing infrastructure. Many families find the ideal solution is a combination of both. Learn more in our Whole House Filtration Guide.
Choosing and Maintaining Your Water Filter
Selecting the right under sink water filter arlington va involves understanding your household's needs and your specific water quality.
Assessing Household Needs
Consider your family's size and daily water consumption to determine the system capacity and flow rate you need. The most crucial step is understanding your water test results. A professional water quality analysis reveals the specific contaminants in your supply, such as lead from old pipes or high levels of PFAS. This data allows you to choose a system certified to remove those exact contaminants, ensuring effective treatment.
Filter Lifespan and Routine Maintenance
An under sink water filter arlington va requires routine maintenance to function properly. Filters become saturated over time and must be replaced. For most RO systems, pre-filters are changed every 6-12 months, while the RO membrane can last 1-2 years, depending on water quality and usage. Following the cartridge replacement schedule is essential for maintaining water quality and preventing issues like slow flow or bacterial growth. Annual sanitization is also recommended for some systems.
Professional Installation Benefits
While simple filters can be a DIY project, multi-stage under sink water filter arlington va systems require professional installation. These advanced systems involve drilling for a dedicated faucet, making complex plumbing connections, and ensuring compliance with local codes. Our certified technicians ensure your system is installed correctly for optimal, leak-free performance. We also offer maintenance services, including filter change reminders and replacements, taking the guesswork out of upkeep. Learn more in our Water Softener Installation Benefits guide.
Key considerations for your under sink water filter in Arlington VA
When choosing your system, look for these features:
- Filtration Stages: More stages, like sediment, carbon, and RO, offer more comprehensive protection.
- NSF/ANSI Certifications: This third-party verification proves the filter performs as advertised.
- Water Flow Rate: Ensure the system can keep up with your family's needs, especially during peak times.
- Dedicated Faucet Options: Choose a style and finish that complements your kitchen decor.
- Remineralization Features: Some systems add beneficial minerals like calcium and magnesium back into the purified water to improve taste and alkalinity.

Yes. High-quality Reverse Osmosis (RO) systems are extremely effective at removing serious contaminants.
